Abstract

The invention relates to a method for calendering paper, especially with so-called glassine calendering. The calender comprises press rolls arranged successively in the paper advancing direction whereby, at least between some of rolls, there are formed press nips for passing paper therethrough. Each press nip is preferably formed by a pair of rolls, one of which is hard and the other elastic. Paper is advanced into the calender at an initial moisture X within the range of 12 % </= X </= 25 %, at least one of the press nips having a calculable line pressure arranged higher than 250 kN/m. In operating conditions, the ratio X/LP between paper moisture X and calculable line pressure LP is maintained in the press nips within certain limits in a manner that the maximum value of ratio X/LP divided by the minimum value of ratio X/LP gives a reading Y, which is Y </= 2.15, whereby X refers to the moisture percentage of paper and LP is a line pressure at a particular press nip expressed as a quantity kN/m (kilonewton/meter). The invention relates also to a paper manufactured according to the method.
